A wooden cutting board is cleaned with hot water, detergent, and scrubbing, but it should not be left soaking or stored wet. Excess water can swell fibers and open joints; prompt drying and a smooth surface extend board life without sacrificing hygiene.
Wash promptly without soaking
Scrub both faces and edges with detergent and hot water, then rinse. Do not leave the board sitting in a full sink because uneven water absorption can warp or crack the wood.
Use a wood-compatible sanitizing method when needed
After high-risk raw foods, use a sanitizing method recommended for boards and observe the contact time. Do not combine disinfectants or assume household vinegar replaces any required sanitizing procedure.
Dry on edge so both faces can breathe
Remove excess water with a clean towel and place the board upright or raised. Storing it flat and wet against a counter keeps one face damp much longer.
Sand light wear and replace deeply cracked boards
A rough surface can be refinished according to the wood and finish, followed by food-safe board oil when appropriate. Deep cracks or open joints that trap food are a reason to replace the board.
